Commerce City Tree Programs

Trees are a significant part of Commerce City’s urban environment, providing beauty, shade, and ambiance. Click here for more information about the city of Commerce City’s tree programs.

Emerald Ash Borer

Commerce City expects all property owners to manage and treat their Ash yard trees. Check out the Ross Tree EAB Handbook to understand your treatment options.

Tri-Level Fertilization Program

Ross Tree’s started its popular Tri-Level Fertilization Program in 2024. We use proprietary feeding formulations to help trees flourish in Denver’s arid climate and poor soils. The program has three feedings per year rather than two.

You can still submit this request — tell us about your trees in the Project Details below and we’ll reach back to see if we can help.

About timing: we can’t guarantee a specific time — our arborist is usually out after 10am, and the day’s route isn’t set until that morning. The good news: you don’t need to be home for the visit. If you’d prefer, we can have him call you when he’s on his way.
Sorry — we can’t process this combination through the website.
Please call us during business hours so we can help.
Tree insect control in Denver

Leading Innovator in Tree Insect Control

Ross Tree is the first tree company to offer systemic insecticide treatments for tree borers, beetles, aphids, and scales in the late 1990s. Trunk injections ensure that only the tree gets the product, not the surrounding environment. However, spraying is sometimes warranted for insect infestations that need immediate treatment.

Summer tree care in Denver

Summer Tree Care Tips

Summer is an excellent time to get your trees ready to withstand Denver’s unpredictable weather. Ross Tree recommends deep rooting feeding at least two times during the growing season. Proper tree pruning forms a dominant leader and thins out the crown to withstand mechanical breakage from snow and wind.
